Specifically, the first driving mechanism 260 may be disposed on a side of the backlight layer 224 away from the display layer 222, i.e., a bottom side of the backlight layer 224. The first drive mechanism 260 may also be disposed on the side of the backlight layer 224. Since the backlight layer 224 includes the adhesive frame, the bottom and side surfaces of the adhesive frame are strong and can bear the weight of the first driving mechanism 260.
It is understood that when the first driving mechanism 260 is disposed on the backlight layer, the display assembly 20 of the present application may include the first display screen 220, the second display screen 240, and the first driving mechanism 260.

The first drive mechanism 260 may also be disposed within the housing 60 of the electronic device 100. That is, the electronic device 100 may include a housing 60, a first display 220, a second display 240, a sensor 40, and a first driving mechanism 260.
The first display 220 may be fixedly connected to the housing 60, and the first display 220 and the housing 60 may form an accommodating space for accommodating the second display 240, the sensor 40 and the first driving mechanism 260.

Referring to fig. 5 in conjunction with fig. 3, fig. 5 is a structural diagram of the second display screen shown in fig. 3 in a second state. The rotating shaft of the first driving mechanism 260 may be fixedly connected to the second display screen 240 to drive the second display screen 240 to move and switch the second display screen 240 between the first state and the second state.
As shown in fig. 3, in the first state, the second display screen 240 is disposed opposite to the opening 2242 and the first portion 2221 of the backlight layer 224, and at this time, the user can see the information displayed on the first display screen 220 through the second portion 2222 of the display layer 222, and the user can see the information displayed on the second display screen 240 through the first portion 2221 of the display layer 222 and the opening 2242 of the backlight layer 224, and the first display screen 220 and the second display screen 240 can display information together.
As shown in fig. 5, in the second state, the second display screen 240 is disposed to be offset from the opening 2242, and at this time, the inside of the first portion 2221 is not shielded by the second display screen 240 and the backlight layer 224, external signals can enter the sensor 40 through the first portion 2221 and the opening 2242 of the backlight layer 224, and the sensor 40 can transmit signals through the opening 2242 and the first portion 2221.
In the display assembly 20 and the electronic device 100 of the embodiment of the application, the display layer 222 of the first display screen 220 includes the first portion 2221 and the second portion 2222, when the second display screen 240 is in the first state, and the second display screen 240 is disposed opposite to the first portion 2221 of the display layer 222, a user can see information displayed by the first display screen 220 from the second portion 2222 of the display layer, and the user can see information displayed by the second display screen 240 through the first portion 2221 of the display layer 222, because the first portion 2221 and the second portion 2222 of the display layer 222 are an integral body, the information displayed by the first display screen 220 and the second display screen 240 is transitionally more natural, and no obvious boundary appears. When the second display screen 240 is in the second state, the second display screen 240 and the opening 2242 are arranged in a staggered manner, at this time, the inside of the first portion 2221 is not shielded by the second display screen 240 and the backlight layer 224, signals can enter the sensor 40 through the first portion 2221 and the opening 2242 of the backlight layer 224, and the sensor 40 can transmit signals through the opening 2242 and the first portion 2221, so that the transmittance of the signals of the display assembly 20 is greatly improved. For example, when the sensor is an image capturing sensor, more optical signals enter the image capturing sensor through the opening 2242 and the first portion 2221, which can meet the lighting requirement of the image capturing sensor, realize the under-screen lighting of the image capturing sensor, and greatly improve the screen occupation ratio of the display module 20.
Referring to fig. 6, fig. 6 is a schematic structural diagram of the first display screen shown in fig. 3. The display layer 222 of the first display 220 may include a first polarizing layer 2223a, a driving circuit layer 2224a, a liquid crystal layer 2225a, a color filter layer 2226a, and a second polarizing layer 2227a, which are sequentially stacked.
The first polarizing layer 2223a, the driving circuit layer 2224a, the liquid crystal layer 2225a, the color filter layer 2226a, and the second polarizing layer 2227a may be located within the second section 2222. The backlight layer 224 may be disposed inside the first polarizing layer 2223a, that is, the backlight layer 224 is disposed on a side of the first polarizing layer 2223a away from the driving circuit layer 2224 a.
The liquid crystal layer 2225a may include a plurality of liquid crystal droplets, which are disposed in small cells of the liquid crystal layer 2225a, one cell forming one pixel unit on the first display screen 220. The liquid crystal layer 2225a may further include electrodes and traces, and the electrodes may distort the liquid crystal layer differently under different voltages, so as to change the angle of the light.
The driving circuit layer 2224a may have a plurality of driving units disposed therein, and the plurality of driving units may be disposed in the second portion 2222 of the display layer 222, and the driving units are electrically connected to the liquid crystal to drive the liquid crystal to rotate. Specifically, the driving unit may include a thin film transistor, and the driving unit may control a voltage applied to the liquid crystal, a magnitude, a duration, and the like of the voltage, so that the liquid crystal is deflected by different angles.
A first linear polarizer may be disposed in the first polarizing layer 2223a, and a second linear polarizer may be disposed in the second polarizing layer 2227 a. That is, the first and second linear polarizers are located at opposite sides of the liquid crystal, and the first and second linear polarizers may be located in the second portion 2222 of the display layer 222.
Wherein the first linear polarizer may make the natural light provided by the backlight layer 224 become linear light and then pass through the first linear polarizer. Since a certain angle is also formed between the first linear polarizer and the second linear polarizer, the linear light passing through the first linear polarizer is not always transmitted through the second linear polarizer, so that the first display 220 is represented as a black screen. When a voltage is applied to the liquid crystal of the liquid crystal layer 2225a, the liquid crystal rotates, so that the line light passing through the first linear polarizer continuously deflects by a certain angle, and when the rotating angle of the liquid crystal is consistent with the angle between the first linear polarizer and the second linear polarizer, the line light can pass through the second linear polarizer after the deflection of the liquid crystal, so that the line light is perceived by eyes of a user, and the first display screen 220 can display information.
The driving unit may control a voltage applied to the liquid crystal to control the liquid crystal to deflect at different angles, so that the amount of light passing through the second linear polarizer is different, thereby generating different brightness for the first display screen 220.
The color filter layer 2226a may include a glass substrate, a black matrix, a color filter, and the like. The black matrix can be arranged opposite to the driving unit to shield the driving unit and reduce the influence of the driving unit on light. The color filter may filter the white light emitted from the light source of the backlight layer 224 into color light of different colors, and the color light may be transmitted to the outside of the display layer 222 to enable the first display 220 to display in color.
Among them, a black matrix and a color filter may be positioned on a side of the liquid crystal layer 2225a away from the backlight layer 224, and the black matrix and the color filter may be disposed between the liquid crystal and the second linear polarizer 2227.
It is understood that the backlight layer 224 may be packaged as a whole with the first polarizing layer 2223a, the driving circuit layer 2224a, the liquid crystal layer 2225a, the color filter layer 2226a, and the second polarizing layer 2227a located at the outer side thereof, so that light emitted from the backlight layer 224 does not leak into the electronic device 100, which may affect the display effect of the first display screen 220.
The principle of the first display screen 220 displaying information according to the embodiment of the present application is as follows: light emitted by the light source of the backlight layer 224 enters the liquid crystal layer 2225a formed by liquid crystal droplets after being filtered by the first polarizing layer 2224a, the liquid droplets of the liquid crystal layer 2225a are all in small unit cells, and one unit cell forms one pixel point on the picture. The electrodes in the liquid crystal layer 2225a twist the liquid crystal differently under different voltages, so that the angle of the light is changed, the light continues to pass through the color filter layer 2226 after being twisted by the liquid crystal to form light of different colors, and finally the light passes through the second polarizing layer 2227 and is transmitted out of the display module 20, so as to be received by the eyes of the user.
Under different voltages, the liquid crystal molecules are twisted and changed to different degrees, and further, the light passes through the liquid crystal molecules to be twisted and changed to different degrees. The liquid crystal display component changes the arrangement condition of liquid crystal molecules in the liquid crystal layer through voltage so as to achieve the purposes of shading and transmitting light to display images with different depths and uniform arrangement. By providing the color filter layer 2226a between the liquid crystal layer 2225a and the second polarizing layer 2227a, a color image can be realized.
The second display screen 240 of the embodiment of the present application may be an LED display screen, and the LED display screen may include a light emitting diode matrix panel and a control circuit. The LED matrix panel can be arranged with a plurality of LEDs, the control circuit can control whether the LEDs emit light, brightness, color, etc., so that different LEDs on the LED matrix panel emit light with different colors and different brightness, and users can feel the information displayed by the LED display screen after receiving the light.
It can be understood that the second display screen 240 can control its own led matrix panel to emit light, that is, when the second display screen 240 displays information, it is not necessary to control the liquid crystal to deflect, nor to arrange two polarizers on the upper and lower sides of the liquid crystal to control the light transmission and light shielding.
Based on this, the first portion 2221 of the display layer 222 located outside the second display screen 240 may include a first polarizing layer 2223b, a driving circuit layer 2224b, a liquid crystal layer 2225b, a color filter layer 2226b, and a second polarizing layer 2227b, which are sequentially stacked. The first polarizing layer 2223b, the driving circuit layer 2224b, the liquid crystal layer 2225b, the color filter layer 2226b, and the second polarizing layer 2227b are located in the first section 2221. The second display screen 240 is disposed at a side of the first polarizing layer 2223b away from the driving circuit layer 2224b, that is, the second display screen 240 is disposed at an inner side of the first polarizing layer 2223 b.
The liquid crystal layer 2225b may include a plurality of liquid crystal droplets, each of which is within a small cell of the liquid crystal layer, one cell forming one pixel unit on the first display screen 220. The liquid crystal layer 2225b may further include electrodes and traces, and the electrodes may distort the liquid crystal layer differently under different voltages, so that the angle of the light is changed.
It is understood that the liquid crystal layer 2225a and the liquid crystal layer 2225b may be one body. A single glass substrate may be disposed outside the liquid crystal layers 2225a and 2225b to cover the liquid crystal layers 2225a and 2225b, and a single glass substrate may be disposed inside the liquid crystal layers 2225a and 2225b to support the liquid crystal layers 2225a and 2225b together.
The liquid crystal droplets located in the second portion 2222 and the liquid crystal droplets located in the first portion 2221 are disposed between two glass substrates, and the liquid crystal droplets can freely flow under the action of a voltage. No frame is required to be disposed between the liquid crystal layer 2225a and the liquid crystal layer 2225b to block the liquid crystal in the second portion 2222 from flowing into the first portion 2221, no frame is present between the second portion 2222 and the first portion 2221, and no black frame that cannot be displayed is present between the second portion 2222 and the first portion 2221 when the display assembly 20 displays a picture.
In this embodiment, the first portion 2221 and the second portion 2222 of the display layer 222 are both provided with liquid crystal, and further, when a user views from the outside of the first display screen 220 through the second portion 2222 and the first portion 2221, the user can view information displayed by the first display screen 220 through the second portion 2222, the user can view information displayed by the second display screen 240 through the first portion 2221, and the first display screen 220 and the second display screen 240 are displayed more naturally.
Since the display information of the LED display screen does not depend on the deflection of the liquid crystal, the driving circuit layer 2224b may not be disposed in the first portion 2221, and a corresponding area of the driving circuit layer 2224b of the first portion 2221 may be a hollow structure, so as to increase the light transmittance of the first portion 2221.
It is understood that the driving circuit layer 2224a and the driving circuit layer 2224b may be a whole body, that is, a whole glass substrate may be disposed outside the driving circuit layer 2224a and the driving circuit layer 2224b to cover the driving circuit layer 2224a and the driving circuit layer 2224b, and a whole glass substrate may be disposed inside the driving circuit layer 2224a and the driving circuit layer 2224b to jointly carry the driving circuit layer 2224a and the driving circuit layer 2224 b.
Wherein a position between the two glass sheets opposite to the second portion 2222 may be provided with the driving unit, and a position between the two glass sheets opposite to the first portion 2221 may not be provided with the driving unit. On one hand, only some structures such as metal wires capable of controlling the touch screen function of the first portion 2221 may remain in the driving circuit layer 2224b, and the light transmittance of the driving circuit layer 2224b is greatly improved; on the other hand, the driver circuit layer 2224a and the driver circuit layer 2224b share two glass plates, and the layered structure of the display layer 222 can be made more stable.
It is understood that the metal traces can be replaced with tin oxide material to further increase the light transmittance of the first portion 2221.
Since the display information of the LED display screen does not depend on the deflection of the liquid crystal, the corresponding area of the first polarizing layer 2223b of the first portion 2221 may be a hollow structure to increase the transmittance of the first portion 2221.
It is understood that the first polarizing layer 2223b may not have polarizing properties. That is, the optical film having polarization may not be disposed in the first polarizing layer 2223b, so as to prevent the optical film from blocking the transmission of light, and reduce the light transmittance of the first portion 2221.
Here, the first polarizing layer 2223a and the first polarizing layer 2223b may be a whole, a whole glass sheet may be disposed outside the first polarizing layer 2223a and the first polarizing layer 2223b to cover the first polarizing layer 2223a and the first polarizing layer 2223b at the same time, and a whole glass sheet may be disposed inside the first polarizing layer 2223a and the first polarizing layer 2223b to jointly support the first polarizing layer 2223a and the first polarizing layer 2223 b.
Moreover, a polarizing film may be disposed between the two glass sheets at a position opposite to the second portion 2222, so as to implement the linear polarization function of the first linear polarizer; no other polarizing film may be disposed between the two glass sheets at a position opposite to the first portion 2221 to improve the light transmittance of the first portion 2221. In the embodiment of the present application, the first polarizing layer 2223a and the first polarizing layer 2223b are integrated, so that the layered structure of the display layer 222 can be more stable.
Since the light emitting diodes of the LED display panel can emit light sources with different colors, the first portion 2221 may not be provided with the color filter layer 2226b, and a corresponding area of the color filter layer 2226b of the first portion 2221 may be a hollow structure, so as to increase the light transmittance of the first portion 2221.
It is to be understood that the color filter layer 2226a and the color filter layer 2226b may be integrated, a single glass thin plate may be disposed on the outer sides of the color filter layer 2226a and the color filter layer 2226b to cover the color filter layer 2226a and the color filter layer 2226b, and a single glass thin plate may be disposed on the inner sides of the color filter layer 2226a and the color filter layer 2226b to jointly support the color filter layer 2226a and the color filter layer 2226 b.
A color filter and a black matrix may be disposed between the two glass sheets and at a position corresponding to the second portion 2222, the black matrix and the driving unit block the driving unit, and light emitted by the backlight layer 224 is transmitted to the outside of the display layer 222 through the color filter. The position between the two glass substrates corresponding to the first portion 2221 may not be provided with the color filter and the black matrix, so as to reduce the light shielding caused by the color filter and the black matrix. In the embodiment of the application, the color filter layer 2226a and the color filter layer 2226b are integrated, so that the layered structure of the display layer 222 can be more stable.
A circular polarizer may be disposed in the second polarizing layer 2227 b. That is, the circular polarizer is located in the first portion 2221 on the side of the liquid crystal layer 2225b away from the backlight layer 224. Half of the light can not pass through when the external light enters the circular polarizer, the light passing through the circular polarizer encounters other metal wires in the display layer 222, the angle between the light reflected by the electrode and the light entering originally is 90 degrees, so that the reflected light can not enter the eyes of the external user through the circular polarizer again, the effect of the reflected light on the display effect can be reduced, and the display effect of the second display screen 240 is improved.
Moreover, when the first and second polarizing layers 2223a and 2227a of the second portion 2222 are provided with wired polarizers, the first and second polarizing layers 2223a and 2227a cooperate with each other to reduce the influence of the reflected light on the display effect of the second portion 2222 when the first display screen 220 displays information. Therefore, the circular polarizer is disposed in the second polarizing layer 2227b of the first portion 2221, and the circular polarizer can also reduce the influence of the reflected light on the first portion 3332, so that the first display screen 220 and the second display screen 240 can display information without a significant boundary feeling between the second portion 2222 and the first portion 2221, and the transition between the second portion 2222 and the first portion 2221 is more natural.
With continued reference to fig. 3 and 5, the second display screen 240 in the first state may be located on a side of the backlight layer 224 away from the display layer 222, and the second display screen 240 in the second state may also be disposed on a side of the opening 2242 away from the display layer 222. That is, the second display screen 240 may be completely disposed inside the backlight layer 224, in this case, a gap may be disposed between the display surface of the second display screen 240 and the bottom surface of the backlight layer 224, and when the first driving mechanism 260 drives the second display screen 240 to switch back and forth between the first state and the second state, the second display screen 240 does not touch the backlight layer 224. Moreover, when the second display screen 240 is completely located on a side of the backlight layer 224 away from the display layer 222, the first driving mechanism 260 may only drive the second display screen 240 to move back and forth left and right on the inner sides of the second portion 2222 and the first portion 2221, and does not need to drive the second display screen 240 to move up and down, and the structure of the first driving mechanism 260 may be simpler.
The first driving mechanism 260 may include a motor, a slide rail, and a connecting rod, the slide rail may be disposed at an edge of a bottom surface of the opening 2242 of the backlight layer 224, and the second display screen 240 may be provided with a slider, which is embedded in the slide rail. One end of the connecting rod is connected with the rotating shaft of the motor, and the other end of the connecting rod is connected with the second display screen 240, so that under the action of the motor and the connecting rod, the second display screen 240 can move back and forth on the inner side of the backlight layer 224 along the sliding rail, and the second display screen 240 can be switched between a first state and a second state.
The first driving mechanism 260 may also include first magnets, second magnets, a spring, and an electromagnetic circuit, the two first magnets are disposed on the second display screen 240, the second magnet is disposed on one end of the bottom surface of the backlight layer 224, one end of the spring is connected to the second display screen 240, and the other end of the spring is fixed on the other end of the bottom surface of the backlight layer 224. When the electromagnetic circuit is on, the second display 240 and the backlight layer 224 are under magnetic attraction, and the second display 240 is disposed opposite the first portion 2221, with the spring stretched. When the electromagnetic circuit is turned off, the magnetic attraction between the second display screen 240 and the backlight layer 224 disappears and the second display screen 240 is pulled back to the original position by the spring, i.e., the second display screen 240 is away from the first portion 2221 and opposite the second portion 2222.
It is to be understood that the first driving mechanism 260 of the present embodiment is not limited to the above example, and the first driving mechanism 260 may be other driving mechanisms, such as a cylinder driving mechanism, a motor gear driving mechanism, a motor belt driving mechanism, and the like. The first driving mechanism 260 for switching the second display screen 240 between the first state and the second state is within the scope of the present embodiment, as long as the second display screen 240 can move relative to the first portion 2221.
The electronic device 100 of the embodiment of the application may further include a processor, and the processor may be in communication connection with the first display screen 220 and the second display screen 240 to control the first display screen 220 and the second display screen 240 to display information. It will be appreciated that the processor may control the first display screen 220 to display information alone and the second display screen 240 to not display information; the processor may also control the first display screen 220 and the second display screen 240 to display information simultaneously.
The processor may also be communicatively coupled to the first driving mechanism 260 of the display assembly 20 to control the first driving mechanism 260 to move the second display screen 240, so that the second display screen 240 is switched between the first state and the second state.
Specifically, when the processor receives the first instruction, the processor controls the first driving mechanism 260 to drive the second display screen 240 to move, so that the second display screen 240 is in the second state, as shown in fig. 5, and the second display screen 240 is arranged by being staggered from the opening 2242. At this time, the inside of the first portion 2221 is not shielded by the second display screen 240 and the backlight layer 224, signals can enter the sensor 40 through the opening 2242 of the first portion 2221 and the backlight layer 224, and the processor can control the sensor 40 to respond to the first command, so that the sensor 40 can transmit signals through the opening 2242 and the first portion 2221, the signal transmittance of the display assembly 20 is greatly improved, and more signals enter the sensor 40.
It is understood that the first instruction may be a photographing instruction, for example, when the sensor 40 is an image capturing sensor, and when the photographing instruction is received, the processor performs the above-mentioned operation to realize the photographing operation. The first instruction may also be a proximity detection instruction, for example, when the sensor 40 is an infrared proximity sensor, the processor performs the above-described operation to implement the proximity detection operation when receiving the proximity detection instruction.
When the processor receives a second instruction, such as a display information instruction, the processor controls the first driving mechanism 260 to drive the second display screen 240 to move, so that the second display screen 240 is in the first state. As shown in fig. 3, when the second display screen 240 is disposed opposite to the first portion 2221 of the display layer 222, the processor controls the first display screen 220 and/or the second display screen 240 to respond to the second instruction, so that the user can see the information displayed on the first display screen 220 from the second portion 2222 of the display layer 222 and can see the information displayed on the second display screen 240 through the first portion 2221 of the display layer 222.
It can be understood that the sensor 40 according to the embodiment of the present application may also be disposed opposite to the second portion 2222, please refer to fig. 7 and fig. 8, where fig. 7 is a third schematic cross-sectional view of the electronic device shown in fig. 1 along a direction a1 to a2, and fig. 8 is a schematic structural view of the second display screen shown in fig. 7 in the second state.
As shown in fig. 7, the sensor 40 and the second display screen 240 may be located on the same layer, and a signal directing element 280, such as a reflector, may be located inside the first portion 2221 and the opening 2242.
As shown in fig. 8, when the second display screen 240 is in the second state, the second display screen 240 is disposed offset from the opening 2242, and the signal emitted by the sensor 40 can be transmitted to the outside through the opening 2242 and the first portion 2221 by the action of the light reflecting plate; signals from the outside may also enter the electronic device 100 from the opening 2242 and the first portion 2221, and enter the sensor 40 through the action of the reflector, and the sensor 40 may transmit signals through the opening 2242 and the first portion 2221. The signal guide element is utilized to realize the function of transmitting signals by the sensor 40, the sensor 40 can be located on the same layer as the second display screen 240, the sensor 40 does not increase the thickness of the electronic device 100, and the thickness of the electronic device 100 can be made thinner.
Referring again to fig. 3-5, the sensor 40 can also be disposed opposite the opening 2242 and the first portion 2221.
In the first state, the sensor 40 may be located on a side of the second display screen 240 away from the display layer 222, that is, the sensor 40 may be disposed on an inner side of the second display screen 240, and the second display screen 240 may be located between the sensor 40 and the backlight layer. Also, the projection of the sensor 40 and the second display screen 240 in the first state on the display layer 222 may be located at the first portion, the second display screen 240 blocking the sensor 40.
In the second state, the second display screen 240 is disposed in a staggered manner with respect to the opening 2242, the sensor 40 may also be disposed opposite to the opening 2242 and the first portion 2221, at this time, the second display screen 240 does not shield the sensor 40, and the sensor 40 may directly transmit signals through the opening 2242 and the first portion 2221.
When the sensor 40 is disposed on the inside of the backlight layer 224, with the sensor 40 disposed opposite the opening 2242 and the first portion 2221, the sensor 40 may include a signal transmission surface that can be moved in and out to vary the distance between the signal transmission surface and the first portion 2221.
For example, when the sensor 40 is an image capture sensor, the image capture sensor may perform a focusing operation, i.e., the lens of the image capture sensor may move up and down relative to the base of the image capture sensor to adjust the focal length of the image capture sensor.
Specifically, when the processor receives the third command, the processor controls the sensor 40 to directly transmit the signal through the signal transmission surface. The third instruction may be an instruction that the image capturing sensor receives a request that the image quality of the image is not too high, and the processor directly controls the image capturing sensor to photograph. The third instruction may also be when performing instant photographing, for example, when taking a snapshot, at which time the lens does not need to be moved and takes time to meet the timeliness of the snapshot.
When the processor receives the fourth instruction, the processor controls the signal transmission surface of the sensor 40 to move to the preset position in the direction of the first portion 2221, and then controls the sensor 40 to transmit the signal through the signal transmission surface. The fourth instruction may be that the image capturing sensor receives an instruction with a high requirement for capturing image quality, at this time, the signal transmission surface of the image capturing sensor moves outward, and further, the signal transmission surface may receive more signals through the first portion 2221 and the opening 2242, so that when the image capturing sensor responds to the capturing instruction, a high-quality picture may be captured.
In the electronic device 100 according to the embodiment of the application, the processor controls the signal transmission surface to move toward the first portion 2221 when receiving the fourth instruction, so that the amount of signals entering the signal transmission surface through the first portion 2221 is increased, the path loss of signals transmitted from the signal transmission surface to the outside through the first portion 2221 can also be reduced, and the accuracy of signal transmission by the sensor 40 is further improved.
It is to be understood that, when the sensor 40 is another infrared sensor or an ultrasonic sensor, the third instruction may also be an infrared detection or ultrasonic detection instruction with low execution accuracy, and the fourth instruction may also be an infrared detection or ultrasonic detection instruction with high execution accuracy.
When the sensor 40 is disposed inside the backlight layer 224, the sensor 40 is disposed opposite the opening 2242 and the first portion 2221, the electronic device 100 may further include a second driving mechanism (not shown in the figures). Referring to fig. 9 and 10, fig. 9 is a schematic structural diagram of the sensor shown in fig. 5 in a third state, and fig. 10 is a schematic structural diagram of the sensor shown in fig. 5 in a fourth state.
Wherein, the second driving mechanism can also be connected with the processor in communication, and the second driving mechanism is fixedly connected with the sensor 40. Under the control of the processor, the second drive mechanism may drive the sensor 40 in motion to switch the sensor 40 between the third state and the fourth state. The sensor 40 in the third state and the sensor 40 in the fourth state may each be disposed relative to the first portion 2221.
As shown in fig. 9, in the third state, the sensor 40 is positioned within the opening 2242 of the backlight layer 224, with the sensor 40 adjacent the first portion 2221. The distance between the sensor 40 in the third state and the first portion 2221 is a first distance L1, and the first distance L1 may be the distance between the signal transmission surface of the sensor 40 and the lower surface of the first portion 2221.
As shown in fig. 10, in the fourth state, the sensor 40 is located inside the second display screen 240, the sensor 40 is located at a distance from the first portion 2221, the distance between the sensor 40 and the first portion 2221 in the fourth state is a second distance L2, and the second distance L2 may also be a distance between a signal transmission surface of the sensor 60 and a lower surface of the first portion 2221.
Wherein the first distance L1 is less than the second distance L2.
When the processor receives the third instruction, the processor controls the second drive mechanism to move such that the sensor 40 is in the third state and adjacent to the first portion 2221. The third instruction may be an instruction that the image capturing sensor receives a request that the image quality of the image is not too high, and the processor directly controls the image capturing sensor to photograph. The third instruction may also be when performing instant photographing, for example, when performing a snapshot instruction, at which time the image capture sensor does not need to move and takes time to meet the timeliness of the snapshot.
When the processor receives the fourth instruction, the processor controls the second drive mechanism to move such that the sensor 40 is in the fourth state and away from the first portion 2221. The fourth instruction may be that the image capturing sensor receives an instruction that the requirement for the image quality is high when the image capturing sensor receives the shooting image quality, at this time, the image capturing sensor moves outward, and further, the image capturing sensor may receive more signals through the first portion 2221 and the opening 2242, so that when the image capturing sensor responds to the shooting instruction, a high-quality picture may be taken.
In the electronic device 100 according to the embodiment of the application, when the viewing angle of the sensor 40 is fixed, since the first distance L1 is smaller than the second distance L2, the area of the first portion required by the sensor 40 in the third state is smaller than the area of the first portion required by the sensor 40 in the fourth state, and further, when the sensor 40 according to the embodiment of the application transmits a signal, the area of the first portion 2221 is smaller by being adjacent to the first portion 2221, so that the influence of the first portion 2221 on the display effect of the first display screen 220 is reduced.
It will be appreciated that the processor may control both the first drive mechanism 260 and the second drive mechanism.
Specifically, when the processor receives the first instruction and the fourth instruction, the processor controls the first driving mechanism 260 to drive the second display screen 240 to move left and right, so that the second display screen 240 is in the second state and is opposite to the second portion 2222, and at the same time, the processor controls the second driving mechanism to drive the sensor 40 to move in the outward direction, so that the second driving mechanism is in the third state and is adjacent to the first portion 2221. Signals enter the sensor 40 from the first portion 2221 of the first display screen 220 through the opening 2242 of the backlight layer 224 of the first display screen 220.
When the processor receives the second instruction, the processor controls the second driving mechanism to drive the sensor 40 to move in the inward direction, so that the sensor 40 is away from the first portion 2221 and is in the fourth state, and at the same time, the processor controls the first driving mechanism 260 to drive the second display screen 240 to move left and right, so that the second display screen 240 is in the first state and the opening 2242 is staggered. The processor then controls the first display screen 220 and the second display screen 240 to display information synchronously.
It is understood that if the first command and the third command are received, the processor may only control the first driving mechanism 260 to move the second display screen 240 left and right, so that the second display screen 240 is in the second state and staggered from the opening 2242. At the same time, the processor controls the sensor 40 to respond to the first instruction by passing a signal from the first portion 2221 of the first display screen 220 through the opening 2242 of the backlight layer 224 of the first display screen 220 into the sensor 40.
It can be understood that the second driving mechanism may also include a motor, a connecting rod, and a sliding rail, the sliding rail may be disposed on the edges of two sides of the opening 2242 of the backlight layer 224, and two sides of the sensor 40 may be disposed with a sliding block, and the sliding block is embedded in the sliding rail; one end of the connecting rod is connected with the rotating shaft of the motor, the other end of the connecting rod is connected with the sensor 40, then the motor drives the connecting rod and the sensor 40 to move, the sensor 40 can move back and forth along the sliding rail in the opening 2242 of the backlight layer 224 towards the display layer 222 and away from the display layer 222, and the sensor 40 can be switched between the third state and the fourth state.
Of course, the second driving mechanism of the embodiment of the present application is not limited to the above example, and the second driving mechanism may be other driving mechanisms, such as a cylinder driving mechanism, a motor gear driving mechanism, a motor belt driving mechanism, and the like. A second driving mechanism for switching the sensor 40 between the third state and the fourth state is within the scope of the present application, wherein the second driving mechanism can move the sensor 40 in the inner and outer directions relative to the first portion 2221.

The control instruction may include a first instruction and a second instruction. The electronic device 100 may touch the control instruction according to the type of the touch information on the interface of the electronic device 100 by the user, for example, when the user touches a camera APP of the interface of the electronic device 100, the control instruction is determined to be a first instruction, and when the user touches a video playing APP of the interface of the electronic device 100, the control instruction is determined to be a second instruction.
And 102, controlling a first driving mechanism of the electronic equipment to drive a second display screen of the electronic equipment to move according to the category of the control instruction, so that the second display screen is switched between a first state and a second state.
The first state is that the second display screen is opposite to the opening and the first part, and the second state is that the second display screen is staggered with the opening.
For example, when the type of the control command is a first command, the first driving mechanism 260 is controlled to drive the second display screen 240 to move, so that the second display screen 240 is in the second state and the second display screen 240 is opposite to the second portion 2222 of the first display screen 220, and at this time, the sensor 40 is arranged opposite to the first portion 2221, so that the sensor 40 transmits a signal through the first portion 2221.
When the type of the control command is the second command, the first driving mechanism 260 is controlled to drive the second display screen 240 to move, so that the second display screen 240 is in the first state and is arranged by being staggered with the opening 2242, and a user can see information displayed on the second display screen 240 through the first portion 2221 of the display layer 222 of the first display screen 220.
Referring to fig. 12, fig. 12 is a second flowchart illustrating a control method of an electronic device according to an embodiment of the disclosure; it is understood that the step of controlling the first driving mechanism of the electronic device to drive the second display screen of the electronic device to move according to the control instruction, so that the second display screen is switched between the first state and the second state includes:
1021, if the control instruction comprises a first instruction, detecting the current state of the second display screen;
when it is determined that the control instruction received by the electronic device 100 is the first instruction, the current state of the second display screen 240 is detected. Specifically, it can be determined by the state of the first driving mechanism 260, for example, when the first driving mechanism 260 drives the second display 240 to switch between the first state and the second state through the link, if the link is in the retracted state, it indicates that the distance between the first driving mechanism 260 and the second display 240 is short, at this time, the second display 240 is disposed opposite to the second portion 2222 and is far away from the first portion 2221, and the second display 240 is in the second state.
